The nuptials have certainly been a long time coming for Catelynn and Tyler, who've been dating since they were both in seventh grade.

On an especially sweet note, the couple's eldest daughter, Carly -- who 16 and Pregnant fans will remember as the baby they gave up for adoption after Catelynn gave birth in 2009 -- and Carly's adoptive parents, Teresa and Brandon, were also in attendance, Us Weekly reports. Their younger daughter, 8-month-old Nova Reign, was the flower girl at the ceremony.

Last week, Catelynn proudly showed off their marriage license. "Look what I got @tylerbaltierramtv you're stuck with me forever!" she joked.

For his part, Tyler is clearly just as smitten with Catelynn after nearly a decade together. "I will be marrying my best friend in 3 days, I can't even begin to fathom how blessed I am! #TheLoveOfMyLife #WillNowBeMyWife," he Instagrammed on Thursday, along with a cute pic of the two kissing.
